Deciphering slogans!

I have just tried to work out the meaning of a slogan, written on a red banner which is hanging across the street in which I live. It crossed my mind that this could be an exercise others might be interested in, too.

Slogans are everywhere. On walls at construction sites, red banners across big buildings, or streets. They usually reflect something of the social, economic and political goals of an area or of the whole country.

My little place (small town of about 6000 people) has quite a few and I could keep us provided with slogans for a while...
